AGR Series Stage Hardware Manual Overview

Chapter 1: Overview

AGR series motorized rotary stages provide significant improvements in speed, load capacity, and long-term

positioning performance over previous generations of worm-gear-drive stages. AGR series stages address a

wide range of applications for general purpose positioning in laboratory and industrial uses.

The AGR series of worm gear driven rotary stages are available in both continuous and limited travel

versions. There are five members of the product family whose apertures range from 50 mm to 200 mm in

diameter.

Construction Features

The addition of a larger clear aperture is a key enhancement over previous generations of worm-gear-driven

stages. This feature allows the AGR series to address applications requiring a through-hole or

accommodations to mount an optic, including articulation of beam polarizing lenses, through-holes for

cabling and/or air lines, or vision/camera/inspection applications.

The AGR stage base is fabricated from an aluminum alloy that offers significant weight savings in multi-axis

arrangements and other weight critical applications, while providing high structural stiffness and long-term

stability.

Each stage is designed with two high-precision angular contact bearings with optimal spacing to provide

excellent error motions coupled with high load capacities in a small, compact package.

Flexible Options

Options include flexible motor selections as well as a direct encoder mounted to the stage shaft for

outstanding repeatability and to virtually eliminate hysteresis and backlash. Vacuum-compatible versions

(for use in pressures as low as 10

-6

torr) are also available.

Motor and Drives

Standard AGR stage configurations feature Aerotech’s brushless servomotors. However, all AGR stages

can be outfitted with stepper or DC brush motors. A full range of matching drives and controls are available

for a complete single-source solution.
